Abstract
This disclosure relates generally to video coding and particularly to methods and systems for providing signaling schemes for jointly coding of motion vector difference. An example method for decoding a current video block of a video bitstream is disclosed. The method includes receiving a coded video bitstream; determining, from the coded video bitstream, a flag for a current video block, wherein the flag indicates whether joint motion vector difference (MVD) coding is applied to the current video block; and in response to the flag indicating that the joint MVD coding is applied to the current video block: obtaining, by the device from the coded video bitstream, a joint MVD for the current video block, deriving, by the device based on the joint MVD, an MVD for the current video block, and decoding, by the device based on the joint MVD and the derived MVD, the current video block.
